A sled on ice moves in the ways described below. Friction is so small that it can be ignored. A person wearing spiked shoes standing on the ice can apply a force to the sled and push it along the ice. Choose the one force (A through G) which would keep the sled moving as described in each statement below. You may use a choice more than once or not at all but choose only one answer for each blank. If you think that none are correct, answer choice J.

.A. The force is toward the right and is decreasing in strength (magnitude).

B. The force is toward the right and is increasing in strength (magnitude).

C. The force is toward the right and is of constant strength (magnitude).

D..The force is toward the left and is decreasing in strength (magnitude).

E. The force is toward the left and is increasing in strength (magnitude).

F. The force is toward the left and is of constant strength (magnitude).

G. No applied force is needed.
